Assessment sheet for Greater North Sea sub-region and for five subdivisions

Greater North Sea

Summary

The physical disturbance pressures from mobile bottom-contacting fishing gears varies spatially in the North Sea region with 91% of the grid cells (I-2), and 62% of the surface area (I-3), in the depth zone 0-200m, being fished on average per year for the period 2013-2018 (Table 1). Fishing is aggregated with 90% of the pressure occurring in 41% of grid cells (I-4). The PD method shows an average decline in community biomass of 11% relative to carrying capacity across c-squares (I-6). Most c-squares, 82% (I-7), have an impact score less than 20%.

The L1 method, estimating the proportion of the community with a life span exceeding the time interval between trawling events, shows an average impact of 0.66 across c-squares (I-6). Only 21% (I-7) of the c-squares have impact scores less than 20% (I-7).

Maps of spatial distribution of intensity, sensitivity and economic value and weight of fisheries landings are shown in Figure 1.

All pressure and impact estimates are for areas < 200 meter depth as there is no longevity prediction for deeper regions.

Pressure

The distribution of fishing intensity in the Greater North Sea has a strong spatial variation (Figure 2). Areas of higher intensity occur in the northern North Sea along the edge of the Norwegian Trench and in the eastern English Channel. Areas with lower intensity occur in the western part of the North Sea, and in the deeper parts of the Norwegian trench.

The proportion of area subject to fishing pressure differs between broad-scale habitats and is highest in offshore circalittoral mud (99% of grid cells fished) and circalittoral sand (97% of grid cells fished) (Table 2). Fishing intensity is highest in upper bathyal sediment (average intensity = 5.61 year-1) and offshore circalittoral mud (average intensity = 3.24 year-1).

Total fishing intensity has increased since 2016 (Figure 3). There was a large peak in intensity in offshore circalittoral mud in 2016. Fishing intensity is relatively stable over time in circalittoral sand and offshore circalittoral coarse sediment. The area within which fishing occurred (footprint) showed less variations in time (except for a decline in 2017). This shows that the overall increase in intensity has not affected the spatial distribution of the footprint much (Figure 3, middle panel).

Fishing pressure is aggregated in a relatively small part of the total footprint, both at the regional level as well as at the level of the habitat (Figure 3, right panel). 90% of the effort occurred in between about a third and half of the area. The intensively fished areas represent the ‘core fishing grounds’. These grounds contribute most of the landings and value (Figure 4). Almost 70% of the fishing effort (swept area) and 60% of the landings and value, occur in only 20% of the surface area of the Greater North Sea (Figure 4, red dot).

Core fishing grounds

In this analysis, core fishing grounds are defined as the c-squares with the 90% highest value of landings in the VMS data. Figure 5 below show the percent distribution of the number of years c-squares are within the 90% highest value by metier. If fishing in a metier occurs in the same c-square every year with high value of landings, the bar at the right will be high, meaning that the c-square is within the 90% highest value of landings every year during the period 2013-2018. If a c-square is only within the 90% highest value in one year, it will end up in the bar at the left. The fisheries for small pelagic fish generally have a high variation in space.

Fishing by métier

Intensity, weight and value of landings were estimated for the grid cells that were fished by one MBCG métier, ignoring cells fished by other métiers (Table 3). The métier with the highest landings and value per area fished is the beam trawl fishery for whelks, snails and scallop (TBB_MOL) but note that only a very small area has been fished by this métier. The seines (SDN_DMF and SSC_DMF) have the lowest landings and value per area fished. This is followed by otter trawls that target crustaceans (OT_CRU).

Impact

The impact of mobile bottom-contacting fishing from the PD method shows the areas of highest fishing impact along the slopes of the Norwegian trench in the Skagerrak and western Norway and in the eastern English Channel (note the 200m depth limit in this assessment) (Figure 7, left). High impact areas are also seen along the continental coast of the North Sea, in the southern North Sea and Kattegat. High impact from the L1 method covers a much larger area (Figure 7, right) that largely mimics the map of fishing intensity.

The impact scores of the PD and L1 method are largely constant over time (Figure 8, left panel). Impact varies between habitats (Figure 8 shows the four most extensive habitat types). Of these four habitat types, impact is highest in offshore circalittoral mud and lowest in offshore circalittoral sand. Between 50-80% of each habitat type has a PD impact score <0.2, whereas only 10-40% of each habitat type has an L1 impact score <0.2.

The different métiers were assessed for the grid cells that were fished by one MBCG métier, ignoring cells fished by other métiers (Table 4). As such this estimates the maximum impact compared to the untrawled situation and the impact estimated assuming all other métiers to have impacted the habitat will be less than this. The métier with the highest impact (PD and L1) relative to the value and landings is the otter trawl fishery for crustaceans (OT_CRU). The beam trawl fishery for whelks, snails and scallop (TBB_MOL) has the lowest impact per value and landings but note that only a very small area has been fished by this métier (Table 3).

Métiers differ in their habitat association and impact on each habitat type (Figure 9). Fishing impact on mud is dominated by the otter trawl fishery (OT_CRU and OT_DMF). Beam trawl impact mostly occurs in circalittoral sand. For the three most dominant metiers (OT_CRU, OT_DMF and TBB_DMF), changes in impact over time are limited; there is some decline in impact scores by the otter trawl fishery on crustaceans (OT_CRU) in mud since 2010 (not shown). The two impact indicators are showing similar qualitative patterns but qualitatively differ in predicted impact of OT_CRU and OT_DMF. These differences arise as the PD method uses a four times larger depletion rate for OT_CRU compared with OT_DMF due to a larger gear penetration depth, whereas the L1 method assumes that all fauna are sensitive to bottom trawl disturbance (independent of the gear penetration depth).
